Broken Window sashes

My wife's 2008 Impalas driver side rear passenger window was broken by some object about 3 years ago. This summer the window was acting up as it would stick up when rolling the window down and then drop with a thud. I removed the inside parts and found, what I now learned is called a window sash, was broken. It can be seen in this schematic: W19 DOOR HARDWARE/REAR PART 2;. Fits: Impala, Monte Carlo | Nalley Buick GMC Brunswick (It is the parts that are attached to the window glass in the picture.) This holds the window to the regulator both when rolling it up, and down, which is why it is dropping down and not moving down with the regulator. Stopped at the NAPA store and they said I would have to get them from the dealer. I went to the dealer and it turns out that they are only sold attached to the glass and that glass is $350.

So anyway I'm thinking of gluing what is left of the sash to the window using something. I was thinking of some JB weld but I thought I would ask the forum for any better ideas. I was first thinking of silicone but I think it would be too flexible and would just tear on the down travel. Any thoughts?

JB may do the trick. You may also have good results using one of the PL products, like Advanced. Holds houses together, shouldn't have a problem with a little glass.

just make sure you have everything perfectly clean and de-greased. denatured alcohol. wear gloves so that oil from skin does not get onto glass.

I did think about using some PL 200/375/400/9,000,000 but didn't want to buy a whole tube. However a $6 tube is cheaper than $350 window.

I will make sure all is clean.
